# XWUIChartStepLine

A step-line chart: a fixed-type wrapper around `XWUIChart` (inner type `stepLine`) that draws the series as a stepped line, emphasizing discrete level changes between consecutive x-values rather than smooth interpolation. Supply `{ series }` plus a `block` preset (1-4) and `size`. Use it when the line should only move at known sample points, making each transition explicit.

## Basic Usage

This example renders two series (Series A and Series B) of six monthly values (Jan-Jun) as stepped lines that change level only at each month, at medium size.

description: Two monthly series drawn as stepped lines, moving only at each month so every level change between consecutive months is explicit.
```

## Kubernetes Pod Autoscaling

Replica counts for two services over 24 hours, where the line only moves when the autoscaler acts so each scaling event is explicit.

## Feature Flag Rollout

Progressive feature-flag exposure for two features, where each deliberate percentage bump and pause plateau is explicit.
